Inspired by DYPLED, this Wristwatch Uses BPW34 PIN Photodiodes, Supercapacitor for Power

Peter Misenko’s wristwatch is one-of-a-kind with a 25x8mm 3V 5F supercap as the power source, mounted in such a way that the backplate of the watch is essentially flat (and surprisingly thin!):

Check out the full wristwatch project here and the DYPLED project that inspired this build (and perhaps your next thin LED display project!) here.

5 years of watch development in one master piece of hardware

Features:

– BPW34 solar cells … plastic, small, unbreakable
– ultra High effective step up converter 95% wint minimum 0.4V working voltage
MAX1724 – Thanks for samples form Maxim Integrated
– custom led 4014 display, inspired by https://hackaday.io/whygee https://hackaday.io/project/8693-dypled project
– Supercapacitor capacity gauge

– Supercapacitor can be charged with USB or SUN
